Class
    Foam::multiphaseExternalTemperatureFvPatchScalarField

Description
    Mixed boundary condition for the phase temperature of a phase in an
    Euler-Euler multiphase simulation, to be used for heat-transfer with another
    region in a CHT case.  Optional thin wall material layer resistances can be
    specified through thicknessLayers and kappaLayers entries.
